Prepare MM Data Generic Import
This page describes how to prepare mobile mapping resources for a generic import.
Using the according Orbit Import Templates the described resources can be imported into Orbit.
It is strongly recommend to read first, Concepts of Mobile Mapping and UAS data in Orbit.
Trajectory
Trajectory file
- File format : One ascii *.csv or *.txt file.
- File structure Rows : One record for each trajectory timestamp. Line ends by carriage return char(13) and newline char(10) sequence.
- File structure Columns : Tab separated (char9), headers, with exact order as the example below.
- Value of Coordinates : Any supported coordinate system can be used, Long/Lat order for geographical coordinates, decimal notation, without thousands separator.
- Timestamp : Any supported time reference can be used, decimal notation without thousands separator.

The camera calibration parameters must be entered before Create Run, the 1st step of the Import Run procedure.
To facilitate import, your specific camera calibration values can be registered inside the Orbit template to avoid entering these values at import each time. Contact Orbit Support if assistance is needed.
